VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No; 750,410, dated January26, 1904. Application filed July 24,1901. Serial No. 69,567. (No model.)

To fI/ZZ whom, it may concern:

Be it known that we, FRANCIS E. STANLEY and FREELAN O. STANLEY, citizensof the United States, residing at Newton, in the county of Middlesex andState of Massachusetts, have invented certain new and usefulImprovements in Vapor-Burners, of which the following is aspecification.

Our invention relates to that class of vaporburners where the burningmixture from a mixing-tube is ignited at a series of perforations; andour invention consists in constructing the burner to form a minorchamber oom- Inunicating with a limited number of the perforations andin providing a separate supply of mixture for this chamber to constitutea pilot-light, as fully set forth hereinafter, and as illustrated in theaccompanying drawings, in which Figure 1 is a plan View of our improvedburner and the supply-pipe and automatic device. Fig. 2 is a section onthe line 2 2, Fig. 1. Fig. 2 is an enlarged detail; Fig. 3, a section onthe line 3 3, Fig. 1.

The burner consists of a series of parallel tubes 1, each of whichcrosses a main tube 2 of larger size, the latter being slotted at thetop to aiford a rounded seat in which the crosstube 1 can rest, as shownin Fig. 2, and the two are connected together by a bolt 3. Preferablythe parts are brazed where they meet, so as to avoid any possibility ofleakage. The tubes 1 are perforated at opposite sides of the center,forming two rows of perforations 4: 5, which, as shown, are inclined, sothat the gas on each side of the space intervening between the paralleltubes 1 1 is projected toward the center of the said space, affording abetter mixture with the air than if it were projected directly upward.

The mixing-tube 6 communicates with the main tube 2 and is parallel tothe tubes 1 and receives the jet of vaporized oil from a nozzle 7 of thewell-known automatic regulator B, which is provided with a valve whichcontrols the flow of the gas to the nozzle in the well known mannerexcept that the gas is cut off completely when the boiler-pressurereaches a predetermined point.

A second nozzle 12 is arranged opposite the 7 open end of thepipe 9 andserves to inject a stream of gas thereinto, which mixes with the air andforms a burning mixture and constitutes a pilot-light, and thispilot-light will also constitute a means of maintaining the vaporizationof the liquid fuel by extending the conducting-pipe 13 over the mainburner A and also adjacent to the supplemental or pilot-burner C,consisting of the perforated pipe 9, and the conducting-pipe extends tothe regulator B at the end adjacent to the nozzle 12, so that theregulator does not cut olf the flow to said nozzle, which flow, however,may be cut off by means of a proper valve 14.

By thus providing a mixing-tube and a pilot-light throwing a constantflame onto the vaporizing-tube at all times, even when the inain burneris completely cut oif, we are able to maintain such a forciblejet ofvapor in the pilot-light whenever the main burner is'extinguished thatthe pilot-light cannot possibly be extinguished, as is apt to be thecase when the main burner nearly closed by the regulatorconstitutes thepilot-light.

Without limiting ourselves to the precise construction and arrangementof parts shown, we claim as our invention- 1. A burner having a seriesof parallel perforated pipes communicating with a transversemixing-tube, a section of one of said perforated pipes closed at theinner end and openat the outer end to constitute the mixing-tube of apilot-burner, and vapor-nozzles one opposite and arranged to supplyvapor to each mixing-tube, substantially as set forth.

2. The combination in a burner, of a series of parallel perforatedseparated tubes 1, a mixing-tube communicating therewith, a partition inone of the tubes 1 and a nozzle for supplying vapor to the end of thesaid tube having the partition, and a conducting-pipe communicating withthe nozzle and extending adjacent to the last-named tube, substantiallyas set forth.

3. The combination in a burner, of a series of parallel perforatedseparated pipes 1, a miX- ing-tube communicating therewith, a partitionin one of the tubes 1, and a nozzle for supplying vapor to the end ofthe said tube having the partition, substantially as set forth.

4. The combination in avapor-burner, of a series of perforated parallelbut separated tubes, one of said tubes open at the end and J. W. BACON,JAs. H. GILKEY.
